Hi All

I want to know, How to Execute Hscript, when we open a new file in
Houdini.
I tried it with 456.cmd but it works only when we open an existing
hip file, and not a new file. Also, 123.cmd only works when Houdini starts.

———–Plz Help.

Sure 123.cmd is run when starting hscript, as mentioned over on the mailing list. I suspect you are having troubles with where 123.cmd exists, and/or your HOUDINI variables.

Cheers,

J.C.

Place your command in the 123.cmd file. Make sure the 123.cmd file is in a houdini/scripts folder somewhere on your path. Out of curiosity, what is it that you're trying to execute?

Does 123.cmd get run when you File->Open though? I'm not sure it does….

No. But 456.cmd does.

123.cmd only runs when you start up Houdini.
456.cmd runs whenever you start up Houdini or go File->Open.

If you do a File->New neither gets run and you get a nice clean empty hip file.

Man this drove me crazy for some time and I ended up removing my scripts in the 456.cmd file as I would have it set my fps not knowing it would override what I had set in the file! arrggh!
Now I know.

Hi All………..

Hey Wolfwood, u r right. Thats what I want to ask. When we go to File-> New, no script is executed. I want to execute some script there. What should I do. I think Jason gave me the answer at Odforce. That there is no such script at this momment., in Houdini.
Want to know, if there is any hack for this.

File->New. Shudder… I guess it's just long-time mistrust, but I always start a new Houdini session, and then delete stuff.

SESI: The help for 456.cmd does say that it is sourced upon a File->New
hdox/houdini/content/commands/guide/hscript_events.xml

path/scripts/456.cmd - Houdini runs this script after you open a saved scene or start a new scene with File > New.

Ahem. Maybe it should too.

Are you in the mood for a couple of crazy suggestions? :-)

You could create a hscript file which does the equivalent of File->New (blows everything away with oprm's, etc) and tie that to a hot-key Alias in 123.cmd. For example: put “alias SF10 $HOME/houdini/scripts/myFileNew.cmd” into 123.cmd. Shift+F10 is normally aliased to the Quit Houdini command. You'd probably not store this in $HOME though.

Using the “message” hscript command (and message's buttons) you could replicate the File->New pop-up. Then, add whatever else you want to do in myFileNew.cmd. The trouble is you'd have to try to change user's behaviour: to use Shift+F10 instead of File->New … j'yeah! Good luck with that.

Create an invisible node (in 123.cmd) which has a deletion script on it. . Put your special hscript commands in the deletion script. Then, when everything gets blown-away, the stuff in your deletion script is run! oooh. So Bad.. “That won't go wrong…” – Don't do this, i'm just kidding! … really.

Wait for SESI to fix File->New so that it sources 456.cmd

ben.

Wait for SESI to make all menus call scripts on disk that can be overridden with your own in HOUDINI_PATH.
